Penn & Teller reveal truths about the Obesity epidemic.

What's not to like about the Americans with Disabilities Act? After all, it is supposed to improve life for the handicapped. Penn and Teller interview businessmen and women, along with some handicap advocates, who say that the act is a huge asset to greedy lawyers who file frivolous lawsuits against whole towns, claiming that the businesses are infringing the rights of the handicapped. The end result is that fewer handicapped people end up getting hired, and hence the ADA defeats its own purpose.

Penn and Teller claim the act is far too broad, and individual businesses, not the government, should be able to dictate who they will cater to.

Mount Rushmore is usually seen as a symbol of American pride and ingenuity.
